It's the only product of that type, that I've seen, that places emphasis on gut hydration. The importance of keeping the gut hydrated, even over-hydrated, is key in a successful outcome.

I will let you know how it works, should the need arise. Which is unfortunately a common occurrence with sport horses.

I feed 2 ounces of raw Apple cider vinegar per head per day and besides being good for about everything from coat to arthritis, seems to have eliminated colic bouts in the 2 that I have who are prone to it. I have also eliminated the use of Gastroguard with an aloe based syrup that I mixed myself and tested on a horse that never ate a full meal in his life....until now.

Just make sure that it is RAW apple cider made from whole apples. The crap you get in the grocery story to cook with is cheaply made from the "throw away" parts of the apple like the cores. I get it from the health food store, it comes in glass bottles...or you can get it online. I use the Bragg brand.

lee and perins worchester sause drench with this first sign of collic 99% of time u will not have a problem i have used it and seen it work many timedont ask me y it just dose

Another trainer told me about this....a wild recipe that was a drench of Worcestershire sauce (like 6 bottles) and eggs (dozen) and maybe something else too but I forget....anyway, I tried it on a pony that was impacted and about 2 hours after administering it, the stall walls were COVERED. Pony ended up relieved....and it was pretty cost effective....like you said, I have no idea how or why it works, but it did for me that time, and has for other people as well.
